Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper plastic packaging, in particular to a paper packaging and plastic packaging device and a use method thereof. BACKGROUND

[0002] Paper plastic packaging is a processing technology that transparent plastic film is attached to the front and back of paper through high temperature and high pressure, aiming to enhance the durability and protection performance of paper.

[0003] As a key technology to improve the durability and protection performance of paper, after production is completed, the stacked paper is first neatly covered and fixed by a packaging machine, and then sent to a plastic packaging machine for high temperature and high pressure film processing. However, the edges of the paper stack formed after packaging are sharp 90° right angles, and the sharp edges with a radius usually less than 0.3mm. When the packaged paper stack is transported to the plastic packaging station and contacts and attaches to the plastic packaging film, these sharp edges are likely to cause physical scratches on the surface of the plastic packaging film at the moment of contact, or even directly puncture.

Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0048] Reference Figures 1-13 A paper packaging and sealing device and its usage method include an operating table 1. A conveyor table 2 for conveying packaged paper to the operating table 1 is integrally installed on the side wall of the operating table 1. The conveyor table 2 consists of two parts, including an upper conveyor belt and a lower base. A rotating roller is provided inside the conveyor belt. A rotating motor is fixedly installed on the side wall of the conveyor table 2 to drive the rotating roller to rotate. The rotating roller drives the conveyor belt on the outer wall to rotate, thereby conveying the packaged paper placed on the conveyor table 2 to the operating table 1.

[0049] Both sides of the operating table 1 are fixedly installed with mounting frames 6, and a clamping mechanism is provided inside the mounting frame 6. The clamping mechanism clamps the packaged paper and conveys the packaged paper into the plastic sealing film through the extension and retraction of the electric telescopic rod 604.
